Inkscape 1.3+ "native" version of the SquiggleDraw Processing app.
This extension will convert the brightness or color intensity of a grayscale or color image into sinewave SVG paths that can then be pen plotted, laser engraved, or used for any purpose you desire!
There are user-editable parameters for how detailed the resulting paths are, the intensity and density of the sinewaves, and how the paths are rendered.
This is a complete rewrite with new version of the primary algorithm, taking into account differences in programming language and host application.
Compared to the Processing version, this extension:
- is faster
- can handle large images with ease
- produces smoother "squiggles"
- can output CMYK color separations for use with CMY pens
- can process transparent images (makes background white)
Notes:
-
This extension has only been tested with Inkscape 1.3, but might work in previous versions.
-
CMYK is actually CMY due to the way Inkscape converts RGB to CMYK (they remove K). C + M + Y will produce K when overlapping ("rich black") and with cyan, magenta, and yellow ink pens, plots should mix appropriately.
-
Use of this extension on images created via Inkscape's "Make Bitmap Copy" feature will sometimes produce unexpected results. It is better to create your bitmaps outside of Inkscape.
